In primary HIV infection syndrome, myalgia is quite commonly experienced, occurring in 30% of a Korean cohort (2),  though previously it has been noted to be present in up to a half of patients and that the symptoms could persist for weeks or even months (3). Arthralgia is less common, occurring in approximately a quarter of patients and is very variable in its severity (4), though it was relatively rare in the Korean study (2). Both of these symptoms are best managed with simple analgesia, such as paracetamol, or anti-inflammatories, such as non-steroidal anti-inflammatory drugs (NSAIDs), and rest.
